Michael Milligan (SiREN) has booked a recurring role on Fox’s 24: Legacy. The real-time limited series that chronicles a race against the clock to stop a terrorist attack on U.S. soil. Milligan will play Theo Sterling, a new programmer at CTU headquarters described as a strange combination of computer geek and Fifth Avenue chic. From a modest background, he’s the creator of an augmented reality app that has made him filthy rich. He’s a bit cheeky and certainly unexpected. Milligan recently guested on Tyler Perry’s Too Close To Home and will be onscreen next weekend co-starring in Universal’s SiREN, a feature adaptation of the segment “Amateur Night” from the 2012 horror anthology V/H/S. He is repped by Alexander White Agency and Hg5 Entertainment.

Robbie Kay (Once Upon A Time) is set to recur on Fox’s Sleepy Hollow, which heads into its fourth season after some major changes that essentially constitute a soft reboot, with most of the cast having been revamped and the premise adjusted. Kay will play Logan MacDonald, a handsome Internet star loved by tween girls around the world — including Molly Thomas (Oona Jaffe), the daughter of new series regular Diana Thomas (Janina Gavankar). Kay plays Peter Pan on ABC’s Once Upon A Time, co-starred as Tommy Clark on NBC’s Heroes Reborn and next appears in the features No Postage Necessary and Locating Silver Lake. He is repped by Paradigm and Affirmative Entertainment.
